Forth.Net.Program 2.0.5

Forth.Net

An implementation of the Forth programming language for the .Net Framework. You can use it as a C# library, interactively with a CLI or compile the code to a compact binary format.

Installation

dotnet tool install -g forth.net.program

Usage

# Start the CLI.
nforth

# Interpret some files and exit.
nforth Test1.fth Test2.fth -e bye

# Compile files to binary
nforth Test1.fth Test2.fth -e 's\" myfile.io" save'

Notes

• You save the user portion of the dictionary with S" myfile.io" save. You load it with S" myfile.io" load.
• You save the whole dictionary, system included, with S" myfile.io" savesys. You load it with S" myfile.io" loadsys.
• Calling into .NET APIs is achieved with these simple words. (fyi just static methods with string or numbers for now).

: escape s" System.Uri, System" s" EscapeDataString" .net ;
: sqrt   s" System.Math"        s" Sqrt"             .net ;

• Calling from .NET to Forth is achieved using the public APIs on the Vm class. Look at the Program folder for a simple example.
• Type debug if curious.
• Type nforth --help for less used options.
